Non-rotating wheel cap

ABSTRACT

The present invention relates to a non-rotating wheel cap which is inserted at the center of a wheel rim using fixtures; wherein such cap is used to display printed or adhered decorations; and wherein such decorations remain stationary in an upright position, while the rim is rotating. The preferred embodiment of the present invention comprises: a plurality of fixtures extending from the body of a hollow disk-shaped housing, a small shaft extending from the center of the housing body, a roller bearing; wherein such bearing is press-fitted into a semi-disk omega-shaped weight from one of its faces; wherein the opposite face of such semi-disk omega-shaped weight is engraved with small cylindrical holes; and wherein an outer disk-shaped cover is attached to such weight. The cap of the present invention is also simple in design, since it needs only one roller bearing and includes no bolts or adhesives.

FIELD OF THE INVENTION

The present invention relates to a non-rotating decorative cap which can be fixed to a rotating body, and in particular, the present invention relates to a non-rotating decorative cap which can be fixed at the center of a vertically rotating member such as a vehicle's wheel; thereby showing a non-rotating state of a pattern, emblem or advertisement irrespective to the rotation of a rotating member.

BACKGROUND OF THE INVENTION

Non-Rotating decorative caps are widely known as vehicles' accessories, which are used to display logos, emblems, or advertisements upon; wherein such caps use adhesives in order to be installed, and use transparent protective covers on the displayed item; wherein the transparent cover causes dust to be accumulated between the transparent cover and the displayed item; and wherein such caps vibrate at certain speeds causing the displayed item to vibrate, and thus become unreadable.

To overcome the rotation problem of regular decorative wheel caps which causes the logo, emblem, advertising or pattern of the caps to be unreadable during the motion of the vehicle, a new non-rotating wheel cap must be put in place with an engineered shape that prevents the caps from vibrating. The new cap must be light in weight, easier to install and more stable than those in the prior art, and does not use any protective covers to prevent the accumulation of dust in order for the logo to be readable all the time.

SUMMARY OF THE INVENTION

Through the movement of a vehicle and during the rotation of the vehicle wheels, any decoration; whether it was a logo, an advertisement or an emblem imprinted on a regular wheel cap becomes impossible to be seen and identified clearly, and after the vehicle stops in a static position, the decoration rarely remains in its upright position and usually stops in a tilted manner, therefore, the main purpose of such cap is to exhibit certain decorative shapes clearly.

Having discussed the main flaw in a regular wheel cap, the need for a non-rotating wheel cap that overcomes this flaw becomes apparent, but due to the limitations of acceptable prices paid for wheel caps and due to constructive and design-related issues, the mechanism that keeps the decoration in its upright vertical position in such caps must be cost effective, simple in design, small in size, light in weight and easy to clean, therefore it is a main objective of the present invention to provide a non-rotating wheel cap that is distinguished by these advantageous features.

To achieve the objective of the present invention, all the components of the non-rotating wheel cap disclosed in this invention are press-fitted to each other in order to avoid the usage of bolts and nuts; which would increase the weight of such cap, and accordingly increases the force needed to maintain such cap in its upright position. Such cap is installed in its position at the center of a wheel rim using fixtures, thus, it is easy for the user himself to install and uninstall such cap, whenever he pleases. Narrow spaces are avoided in the cap of the present invention, since these spaces increase the difficulty of cleaning such cap. The decorations displayed on such cap are at the most apparent component on the outer side of such cap, with no transparent surfaces covering the decoration, since these surfaces are known for accumulating mist.

The non-rotating cap of the present invention consists of a hollow disk-shaped housing; wherein fixtures extend from the body of this housing. At the center of the inner space of the housing, a small shaft extends to be press-fitted inside the center of a roller bearing, at the outer circumference of the roller bearing, a semi-disk omega-shaped weight is press-fitted from one of its faces; wherein the opposite face of the semi-disk omega-shaped weight is engraved with small cylindrical holes; wherein an outer disk-shaped cover is attached to the weight through cylindrical extended portions inserted in these holes in order to enclose the space inside the housing. The decoration that is meant to be displayed by the cap of present invention is either printed or adhered on the cover. The cap disclosed in the present invention is capable of maintaining the attached logo/decoration at an upright position during the motion of the vehicle, while having the same size of a regular decorative cap. The light weight of the cap disclosed in the present invention allows for the usage of only a single roller bearing.

BRIEF DESCRIPTION OF THE DRAWINGS

Further features and advantages of the present invention will become apparent from the following detailed description, taken in combination with the appended drawings, in which:

FIG. 1 illustrates a non-rotating wheel cap configured according to the preferred embodiment of the present invention; wherein the components of such cap are shown separately.

FIG. 2 illustrates an exploded view of a non-rotating wheel cap configured according to the preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a non-rotating wheel cap for displaying decorations configured according to a preferred embodiment of the present invention; wherein this embodiment comprises: a hollow disk-shaped housing 1; wherein elastic fixtures 2 extend from the outer side of the housing 1 to circumfuse the housing 1 laterally, at the inner space center of the housing 1, a small short shaft 3 extends from the housing 1 body. Upon assembling the embodied cap, the shaft 3 is press-fitted inside the center of a roller bearing 6, the outer lateral circumference of the roller bearing 6 is press-fitted into a cylindrical hole 5; wherein this hole is perforated in a semi-disk omega-shaped weight 4 from one of its faces; wherein the opposite face of the semi-disk omega-shaped weight 4 is engraved with small cylindrical holes 7; wherein the number of these holes is preferably three holes. An outer disk-shaped cover 9 is attached to the weight 4 through cylindrical extended portions 8, which are inserted in the holes 7; the disk-shaped cover 9 encloses the space inside the housing 1. The displayed decoration are either printed or adhered to the outer surface of the disk-shaped cover 9. The omega shape of the semi-disc 4 is specifically selected to prevent undesired vibration of any exhibited decoration.

From the discussed features of the preferred embodiment of the present invention, it is clearly noticed that the hollow disk-shaped housing 1 can be manufactured based on the central space of a wheel rim, thus, and due to the compact design of the non-rotating wheel cap disclosed in present invention and since these designs enfold the mechanisms needed to keep the upright position of the cap inside the inner space of the housing 1, the cap can be simply inserted in the inner space of any wheel rim with no need to any modifications, in a manner similar to any regular wheel cap.

Excluding the roller bearing 6 and the weight 4; which are made out of metal, all the components of the cap are made of plastic, in order to reduce weight; wherein such reduction in weight enables the single roller bearing 6 to efficiently hold the cap in its upright position.

The non-rotating wheel cap of the present invention has also been tested at a machine that rotates the wheel of a vehicle in order to simulate the actual motion of vehicles. Going at a simulated speed that exceeds 400 km/hr, the non-rotating wheel cap disclosed in the present invention kept at an upright position during the whole period of the test.

Although the above description of the present invention has disclosed the features of the invention as applied to the preferred embodiment; additions, omissions and modifications applied to the details of the embodiment illustrated may be made by those skilled in the art without departing from the essential characteristic of the present invention.
